Stainless steel with austenitic organisation at room temperature becomes austenitic stainless steel, the chromium content is generally between 16%-26%, austenitic mainly by cold working to strengthen the hardness, because of its low carbon content, welding performance is better, corrosion resistance is also very good. It has excellent corrosion resistance and is used more in conventional medical devices, such as: puncture products, handles, and non-critical parts of the product.
